Boost.Assign

Assign assists in assigning series of values into containers. It gives the user an easy way of assigning data, by means of overloaded operator, (the comma operator) and operator()() (function call operator). Although being especially useful for a prototyping-style of code, the functionality of the library is useful at other times too, due to the readable code that results from using the library. It is also possible to use this library to create anonymous arrays on-the-fly using list_of.

The author of Assign is Thorsten Ottosen.

Boost.Filesystem

The Filesystem library offers portable manipulation of paths, directories, and files. The high-level abstractions enable C++ programmers to write code similar to script-like operations that are often available in other programming languages. For iterating thorough directories and files, convenient algorithms are provided. The difficult task of writing code that is portable between platforms with different filesystems becomes feasible with the help of this library.

The author of Filesystem is Beman Dawes.

Boost.Format

This library adds functionality for formatting arguments according to format strings, similar to printf, but with the addition of type safety. One of the primary arguments against using printf and similar formatting facilities is that they are inherently dangerous; there is no assurance that the types that are specified in the format string are matched by the actual arguments. Besides eliminating the opportunity for such mismatches, Format also enables custom formatting of user-defined types.^[4]

^[4] This is not possible with formatting functions using a variable number of arguments through use of ellipsis.

The author of Format is Samuel Krempp.

Boost.Io_state_savers

The Io_state_savers library allows the state of IOStream objects to be saved, and later restored, to undo any intervening state changes that may occur. Many manipulators permanently change the state of the stream on which they operate, and it can be cumbersome at best and error prone at worst to manually reset the state. There are state savers for control flags, precision, width, exception masks, locale for the stream, and more.

The author of Io_state_savers is Daryle Walker.

Boost.Serialization

This library allows arbitrary C++ data structures to be saved to, and restored from, archives. An archive could be, for example, a text file or XML file. Boost.Serialization is highly portable and offers a very mature set of features, such as class versioning, serialization of common classes from the C++ Standard Library, serialization of shared data, and more.

The author of Serialization is Robert Ramey.
